Getting Started with C# NanoFramework: WIFI Scanning, Connecting, and HttpWebRequest on ESP32

Congratulations! The new board has finally arrived, without further ado, let’s get started.

The main function of the ESP32 is WIFI. With WIFI, it can directly connect to the home WIFI router and access the internet. At this point, it acts like a small computer or smartphone, making it very convenient to connect to the internet.

The ESP32 WIFI has three main modes:

1. AP mode (WIFI router mode), where it becomes a router itself, providing WIFI services to other devices.
2. STA mode

Using ESP_NOW for Inter-device Communication on ESP32 S3 with Arduino

0x00 What is ESP_NOW?

ESP-NOW is a wireless communication protocol defined by Espressif that allows for direct, fast, and low-power control of smart devices without a router. It can coexist with Wi-Fi and Bluetooth LE.

Currently, it supports multiple series of SoCs such as ESP8266, ESP32, ESP32-S, and ESP32-C. ESP-NOW is widely used in smart home appliances, remote control, and sensor applications.

Why is the ESP32 So Popular?

❝
The ESP32 is something many people may have heard of or used. If you have previously used an Arduino development board, you might have come across it as well. The ESP32 refers to a series of chips and modules produced by Shanghai Espressif Systems, rather than a specific chip, which is something to note. Today, I will introduce Espressif's chips.
Espressif's Chip Family
Espressif has five system products, namely: ESP32S series, ESP32C series, ESP32H series,ESP32, and ESP8266 (Yes, except for the ESP8266,
